Application filed March 22, 1900.

To all whom it may concern: I

Be it known that I, CLIFFORD SHAW, hydraulic engineer, of No. 100 Broadway, in the city and State of New York, have invented certain new and useful Improvements in Apparatus for Lifting Water, of which the following is a specification.

One way of lifting water has been to deliver the water into a reservoir well or pit in which watenlifting mechanism is placed. Where the system known as the Bacon air-lift is employed for raising water, the reservoir well or pit will have a depth proportionate to the height to which the water is to be raised, as will be understood by every one skilled in the art. Where such reservoir-wells are used for elevating water or other liquids that contain sediment, there is always danger of the mechanism becoming so-clogged when out of use that it will not start again properly.

The object of the present invention is to provide means for preventing the excessive settling of sediment in or around the waterlifting mechanism. This object I attain by inelosing the lower portions of the apparatus entirely when out of useas, for example, by gates or Valves, which either close the mouth of the well or close the well farther down, near the intake-mouth of the pump or uptake mechanism employed.

In the preferred forms of the invention an air-lift is employed, and the Valve or gate should be placed so far above the intakeopening of the uptake-pipe that such sediment that may have accumulated above the valve or gate will not clog the mechanism when the valve or gate is open. As a matter of convenience I prefer to place the valve or gate either just beneath the lowest level at which the water stands in the well or else (where the pit is a comparatively large reservoir having an eight or ten inch immersionwell or smaller pit extending downward to give the necessary depth of immersion) at the head of the immersion pit or well.

To these ends the invention consists in the apparatus or combinations as hereinafter claimed and as illustrated and described in some of its preferred forms in the following description.

Serial No. 9,696. (No model.)

Figure l is a sectional view showing the most approved form of the invention. Fig. 2 is a detailed view showing a slight modification. Figs. 3, 4, 5, 6, and 7 show other modifications.

In Fig. 1 the larger portion of the reservoir or pit is shown at b; but this might also be taken as illustratingashaft in a mine or, indeed, any open space, because the immersion pit or well proper is at o, the uptake-pipe for the air and water shown at d, and the air-pipe at e. I have shown the air-pipe e surrounding the uptake-pipe; but it is not even necessary that either pipe should be within the other. At 7t is a valve-seat, with which the valve j cooperates. The water or other liquid flows into the well 0 through the valveseat h when the valve is open. The valvejis secured to the outer pipe 6, so as to be moved with it. Screws Z are provided for raising go the outer pipe e, either with or without the inner pipe (1. Consequently the screws Z control the valvej. The operation of this form of the invention is as follows: When the well is in use-that is to say, is operatingthe valvej is open, as in Fig. 1. The water or the liquid passes through the open valve down into the well 0 and thence up through the uptake d. So far'as the present invention is concerned the depth of water above the valvej is unimpor- 8o tant. The screen m serves to prevent logs and other obstructions from getting into the valve and well. When the well is stopped and the air shut off, the valvej is lowered into place and may so remain until the operation is resumed. WVhen not in operation, only the sediment within the well a and beneath the valve can settle about the inlet-opening in the pipes d and c. Any mud or other sediment settling from the water above the valve j is 0 prevented from entering the well 0. When the operation is resumed, the flow of water through the valve j carries with it some of the sediment that has settled above the valve; but this does no harm, as it cannot settle 5 when the well is in operation.

In Fig. 2, p is a cam controlled by the lever r and operating, when turned, to raise or lower the collar 3, which corresponds to the collar 3 in Fig. 1, and therefore controls the valve.

' the water-raising mechanism, may be raised,

Many other means of controlling the valve have suggested themselves to me, but are not essential in matters 'of detail to the invention.

In Fig. 3 the valve j is shown movable independently of the air-lift mechanism, a controlling-rod being provided to actdirectly on the valve.

In Fig. 4 the valve 3', either with or without and lowered and supported at one or more points by levers u and adjusting-screw 4;, which operates upon a screw-threading nut 12" to raise and lower the nut and the end of the lever a, as shown.

In Figs. 5 and 6 a rotary valve j, having several leaves or'vanes of segmental or fan shape, is shown cooperating with a similar valve h. The valve'j is secured to the outer pipe of the water-raising mechanism, so that by turning the pipe the valve may be opened and closed. e

.In Fig. 7 the valve is in the form of a gatevalve j" and is entirely dissociated from the air-lift pipes. Such form is desirable where the water is delivered to the well 0 through a pipe or conduit w and where the brickwork or other flaw m in the vicinity of the valve is dry, or at least readily accessible. In dotted lines, however, at z I show that the valvestem may extend upward to any desired height, so as to control the valve from above. The specific subjects-matter of Figs. 3, 4, and

'7, so far as they cannot be claimed herein,

form the subject of specific divisional applications filed hereafter. I

. I have described only the preferred forms 1 of the invention as adapted for special uses.

The invention is in principle equally well adapted to a great many other conditions, which I will not attempt to enumerate.

, The novel and characteristic features which I believe distinguish my invention from the prior art are set forth in the following claims.

I claim- 1. In combination in apparatus for raising liquid of the type employing a submergence pit or well and an air-lift mechanism, a valveseat through which liquid is admitted to the air-lift mechanism, and a valve connected to and actuated by the air-lift mechanism, 'substantially as set forth.

2. In combination in apparatus for raising liquid of the type employing a submergence pit or well and an air-lift mechanism, a valveseat through which liquid is admitted to the air-lift mechanism, and a valve connected to and movable with the air-lift mechanism, substantially as set forth.

' 3. In combination in apparatus for raising water, wherein the water to be raised is first delivered into a reservoir well or pit, air-lift mechanism for raising the water from the well or pit, combining an uptake and a downtake pipe, anda valve secured to one of said pipes for closing the Well or pit, substantially as set forth. 1

4:, In combination in apparatus for raising water, wherein the Water to be raised is first delivered into a reservoir wellor pit, air-lift mechanism for raising the Water from the well or pit, combining an uptake and a downtake pipe one within the other, a valve secured to the outer pipe and movable therewith, and a valve-seat therefor through which the water passes to the well or pit, and means for moving the said outer pipe and valve to open and close the well or pit, substantially as set forth.
